Subject [jira] [Commented] (DERBY-3676) Make the toString() method of Derby PreparedStatements print out SQL text with ? parameters replaced by the values that have been set so far
Date Wed, 17 Aug 2011 18:40:28 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086507#comment-13086507
] 

Dag H. Wanvik commented on DERBY-3676:
--------------------------------------

Looks good. One nit: I presume the single ":" in "parameter #1:" is
part of the lead text for printing that parameter, indicating "this is
what it is". If so, would it be more readable to have something else
that "::" to delimit the parameters? (presuming "::" is a delimiter)

Something like:

CacheId:6c44409f-0131-d546-4475-0000030d5ec8::INSERT INTO
Orders1(ID,dBlob) VALUES(?,?) [parameter #1: 1] [parameter #2:
BLOB(org.apache.derby.iapi.types.RawToBinaryFormatStream@5c2a1ed)]

Or even more terse (my preference):

CacheId:6c44409f-0131-d546-4475-0000030d5ec8::INSERT INTO
Orders1(ID,dBlob) VALUES(?,?) [#1: 1] 
[#2: BLOB(org.apache.derby.iapi.types.RawToBinaryFormatStream@5c2a1ed)]

(omitting the text "parameter ")

> This topic came up in the following email thread on the user list: http://www.nabble.com/PreparedStatement.toString%28%29---nice-formatting-td17250811.html#a17250811
Here's what the thread requests: 
> "In mysql, a toString() on a PreparedStatement will do this, eg "select x
> from foo where x.a = ?" will become "select x from foo where x.a = 1" with
> the appropriate setValue() call."
> At first blush, this seems like it might be a simple project for a newcomer.
